    pyrogens
  • rate at which heat is produced when body is at rest?
    basal metabolic rate
  • the BMR depends on a persons?
    body surface area
  • the basal metabolic rate is affected by which hormone?
    thyroid
  • what other hormones affect the BMR?
    epinephrine, norepinephrine, testosterone
  • because of their increased levels of testosterone, men usually have a __ BMR?
    higher
  • voluntary muscle movement has what effect on BMR & heat production?
    increase
  • what increases the bodies heat production x5?
    shivering
  • the thermostat that controls body temp by feedback mechanisms?
    hypothalamus
  • as the body heat rises, the hypothalamus sends signals for the body to do what (3) things?
    vasodilation, sweating, inhibition heat production
  • as the body temperature drops, the hypothalamus sends signal to the body to do what?
    vasoconstriction, shivering
  • (4) ways that heat is lost?
